SAW-SUPPORT FOR UNDERCUTTTNG.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed May 2, 1907. Serial No- 371,539.

To all whom it may concern:

Be it known that I, ANGUS E. SHROY, a citizen of the United States,residing at La Center, in the county of Clarke and State of Washington,have invented a new and useful Improvement in Saw-Supports forUndercutting, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates to improvements in supports for saws when in usefor cutting a felled log from beneath.

It has for its object to provide means for guiding and supporting thesaw blade in proper position which can be easily and quickly applied bythe workman in connection with his ax. A

The invention consists in the features of construction and combinationsof parts hereinafter described and specified in the claims.

In the accompanying drawing illustrating the preferred embodiment of myinvention: Figure l is a perspective view of the clamp and rollerattachment. Fig. 2 is a perspective view of the clamp alone. Fig. 3 is adetailed view of the roller carrying pin or bolt, showing the roller insection, and Fig. 4 shows the clamp applied for use.

Referring more particularly to the drawings, 0 designates the clampwhich is preferably made of a strip of resilient metal bent as shown toform arms 0 and C. and ahead 0 The arms of the clamp are adapted to gripthe handle A of the ax A by means of the bolt b passed through holes 1)and b in the ends of said arms and carrying a thumb nut b The head ofsaid clamp is bent to form a loop h which is substantially circular incross section and adapted to receive the bolt or pin R carrying theroller R between its head and a nut N. Said bolt R is secured in placeby means of a thumb nut R The opposite sides of said loop h are providedwith openings or passages it also adapted to receive the bolt or pin RIt will thus be seen that said bolt may be arranged either in line withsaid clamp or at right angles thereto to suit different requirements asthe log L is being cut through as illustrated in Fig. 4.

The roller B should revolve freely on the unthreaded portion of the boltR. Said roller has a series of square grooves g in its outer surface, inany one of which the rear edge of the saw S (Fig. 4) is adapted to run.The grooves should be wide and deep enough to permit the back of the sawto slide easily therein when operated.

At the left hand side of Fig. 4, the ax is driven into the log in avertical position and the bolt R is passed through the openings h of thehead of the clamp.

At the right hand side of Fig. 4, the axis driven into the log in ahorizontal position and the bolt R is passed through the loop 71.

The clamp is of course adjustable on the ax handle to allow the sawsufficient play when resting in one of the grooves.

I claim:

1. A clamp of the character described, adapted to be fastened upon asupport, said clamp having resilient arms and a head provided withpassages arranged at right angles to each other, a clamping bolt passedthrough perforations in the ends of said arms, a bolt adapted to bepassed through and rigidly secured in either of said passages in saidhead, and a grooved roller mounted freely on said bolt and adapted tohold and guide a saw for undercutting.

2. A clamp of the character described, adapted to be fastened upon asupport, said clamp comprising a strip of resilient metal bent to formarms and a looped head having openings or passages through the oppositesides thereof, a bolt adapted to be passed through and secured either insaid loop or in said passages, and a grooved roller mounted freely onsaid bolt and adapted to hold and guide a saw for under cutting.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

ANGUS El SHROY.
